Wow, lots of questions! Welcome aboard, by the way...
As I have heard others say, "the only dumb question is the one that isn't asked."
Your "buzzing or humming" sound is surely due to bad electrolytics. All of the paper and electrolytic capacitors are going to have to be replaced. Read here for more on this subject:

Your not hearing anything on FM is, again, probably bad capacitors. Although a failed tube is not out of the question, you may be surprised to know that most of the tubes in an old radio are usually still good.
You may want to read this thread on another 47-1230:

I don't own a 47-1230, so can't comment on the cut wires.
The preset button switches are probably dirty. DeoxIT is your friend here.
Your cabinet looks like it has been stripped at some time in the past. Sanding is not the answer. You could easily sand through the veneer. There are proper procedures to follow when refinishing a radio cabinet; I would have to defer to the guys here who are much more knowledgeable than I when it comes to refinishing. Steve Davis, Gary Rabbitt, etech, and others whom I cannot think of right now (apologies if I left your name out, folks). Send them a PM if they don't chime in here; they are very helpful fellows as well as being quite knowledgeable.
What seems like a transformer that the audio cable from the record changer connects to, is a transformer. An impedance matching transformer, to be exact.
The original changer may very well be repairable. As for the cartridge, a magnetic cartridge with a 78 rpm stylus could be used in place of the original "Dynamic" cartridge. The 47-1230 has a phono preamp built into the chassis, so this is an ideal setup for a magnetic cartridge.
